The hazards of kitchen fumes

The catering industry produces a significant amount of oil smoke and exhaust gas while cooking and processing food, which can be harmful to human health. The composition of oil fumes is complex, with as many as 20 different pyrolysis products from various edible oils, including aldehydes, ketones, hydrocarbons, fatty acids, aromatic compounds, and heterocyclic compounds. Different foods produce different types of volatile substances when cooked at high temperatures, with hundreds of potential substances.

 

The particulate matter (TSP) emitted by the catering industry is primarily PM2.5, which accounts for 76.91% of particulate matter. Food and beverage fumes are a direct source of PM2.5 emissions, and soot pollutants can worsen the impact of haze. Inhaling kitchen fumes can harm sensory organs and expose individuals to carcinogenic substances. The long-term effects of exposure to these fumes can be serious, and it is important for individuals working in the catering industry to take proper precautions to protect themselves and others.

The scope of application of electrostatic precipitator air purifier

Electrostatic precipitator air purifiers (ESPs) are commonly used in commercial restaurants in countries such as China, the United States, and the United Kingdom to reduce the environmental impact of kitchen fumes. ESPs are a necessity for opening a commercial restaurant in these countries.

 

They are commonly used in restaurants near residential buildings, factory staff restaurants, Japanese restaurants, Korean restaurants, Chinese restaurants, airport restaurants, restaurants in railway station waiting halls, and restaurants in high-end shopping malls.

 

In general, ESPs are suitable for use in almost all commercial restaurants. These devices work by using an electrical charge to attract and remove particulate matter from the air, effectively reducing the amount of pollution generated by the kitchen. This can improve air quality and reduce the health risks associated with exposure to kitchen fumes.

Advantages of electrostatic precipitator air purifier

Electrostatic precipitator air purifiers (ESPs) have several advantages, including their excellent purification efficiency, modular design, low operating noise, and automatic pressure regulation system.


ESPs from DHF have a purification efficiency of up to 98%, making them highly effective at removing particulate matter from the air. This can improve air quality and reduce the health risks associated with exposure to kitchen fumes.
The modular design of the electric field (cell) allows the ESP to be easily assembled in series or parallel to suit the size of the air volume. This makes installation simple and convenient.


The low operating noise and resistance of ESPs also make them cost-effective to run. The automatic pressure regulation system can extend the cleaning cycle of the ESP, reducing the labor costs associated with maintenance. This can help to save money and improve the overall efficiency of the device.

Working principle of electrostatic precipitator air purifier

 

The working principle of electrostatic precipitator air purifiers (ESPs) is based on Coulomb's law. In order to apply a Coulomb force to a small particle (such as an oil particle), the particle must be polarized or charged. An electric field is established, which drives the charged oil particles towards the plates under the action of the Coulomb force (electric field force), allowing them to be collected.

 

When air containing oil fumes is drawn into the ESP by a fan, a front filter intercepts some of the larger oil particles. As the air flows into the high-voltage electrostatic field (cell), the particles of the oil smoke gas are ionized by the high voltage under the action of the high-voltage electric field.

 

The ionized particles are attracted to the positive and negative plates of the electric field (cell) under the action of the electric field force and the air flow of the adsorption electric field (cell). The particles are collected on low-pressure plates and flow to the oil collection pan by their own gravity. The remaining micron-sized oil mist is degraded by the electric field (cell) into carbon dioxide and water, which are then exhausted through pipes as clean air.

 

At the same time, under the action of the high-voltage generator, the air in the electric field (cell) produces ozone, which removes most of the odor in the flue gas. This helps to improve the air quality and reduce the impact of kitchen fumes on the environment.

The housing of the ESP is made of high-quality sheet metal, which can be finished in a range of colors to suit the customer's preferences. OEM (original equipment manufacturer) services are also available, allowing customers to have their own branding and logo added to the ESP.

 

The low MOQ (minimum order quantity) makes it easy for customers to explore the market and test different branding options. These customization options can help to make the ESP air purifier more attractive and appealing to customers.

Excellent purifying effect

DHF electrostatic precipitator air purifiers (ESP) have excellent purifying effects, with purification efficiencies (DOP) of 98%, 85%, and 70%. Consumers can choose the appropriate purification efficiency (DOP) based on the requirements of the local government and surrounding residents.


For areas where the emission concentration of oil fumes must be less than 1 mg/cubic meter, a model with a purification efficiency (DOP) of 98% is recommended. This ensures that the air purifier can effectively remove the majority of particulate matter from the air, improving air quality and reducing the health risks associated with exposure to kitchen fumes.


For areas where the emission concentration of oil fumes must be less than 2 mg/cubic meter, a model with a purification efficiency (DOP) of 85% is recommended. This provides a good balance between purification efficiency and cost.


For areas that are far from the city center and located on high-rises, a model with a purification efficiency (DOP) of 70% is recommended. This option is less expensive, making it suitable for customers with limited budgets.


These different options allow customers to choose the ESP air purifier that best meets their needs and requirements.

Advantages of plate cell

Smaller size in the same DOP

DHF electrostatic precipitator air purifiers (ESP) have a smaller size compared to other ESPs with the same purification efficiency. The plates of the high-voltage electric field (cell) are made of 2mm aluminum alloy and 304 stainless steel, and the pole plates of the low-voltage electric field are made of 0.8mm aluminum alloy. The distance between the plates is 7mm, which increases the density and purification efficiency (DOP) of the ESP.

 

In contrast, honeycomb electric field (cell) ESPs have only a high-voltage area, and the material is a 0.3mm galvanized sheet. While these ESPs have a high purification efficiency, the oil pollution collection area is only half that of the plate electric field ESPs, and the equipment is larger and more difficult to install. DHF ESPs provide the same level of purification efficiency in a smaller, more compact design, making them easier to install and use.

Longer cleaning cycle time of plate cell

Plate electric field (cell) electrostatic precipitator air purifiers (ESP) have a longer cleaning cycle time compared to honeycomb electric field (cell) ESPs. After the plate electric field (cell) is assembled, the plates are perpendicular to the ground, and the collected oil automatically flows to the sewage outlet at the bottom of the equipment due to inertia.

 

This allows the ESP to operate for a longer period of time before it needs to be cleaned, reducing the amount of maintenance required. In contrast, after the honeycomb electric field (cell) is assembled, the cylinder is parallel to the ground, and part of the collected oil will accumulate at the lowest point of the cylinder.

 

This can cause the ESP to need to be cleaned more frequently, resulting in shorter cleaning cycles and more complex maintenance. DHF plate electric field (cell) ESPs have a longer cleaning cycle time, which makes them more convenient and cost-effective to operate.

Easier cleaning

Plate electric field (cell) electrostatic precipitator air purifiers (ESP) are easier to clean than honeycomb electric field (cell) ESPs. After the plate electric field (cell) is soaked, it only needs to be rinsed with a high-pressure water gun and dried before it can be used again.

 

This is a simple and straightforward process that can be completed quickly and easily. In contrast, after the honeycomb electric field (cell) is immersed, each cylinder needs to be cleaned individually. This requires careful work to avoid damaging the electrodes of the cylinder, which can be time-consuming and labor-intensive. DHF plate electric field (cell) ESPs are easier to clean, making them more convenient and cost-effective to maintain.
